I was too terrified of tearing and episiotomy in a VB so I researched and here is what I found can reduce the risks:
- Remaining fit/exercising during pregnancy: women who exercise during pregnancy have a lower risk of instrumental delivery, which is linked to a higher incidence of tearing
- Giving birth on any other position than lying on your back: on your side, on all four, squatting, etc...
- Labouring down, gentle pushing, as opposed to forceful pushing
- Perineal massages
I wrote a birth plan that insisted on the second and third point, eventually, it all went tits up during labour: I had a very long labour (25 hours) as my waters broke before labour started, though it wasn't that bad with epidural; though I asked for a "walking epidural" in order to remain mobile during labour, even with the lowest dose of epidural my blood pressure had dropped too much to be able to walk, or even position myself in all fours; I had to give birth on my back as it was the only position the baby would descend and I had to do forced pushing as the baby's heart rate was starting to slow down and I had to get him out soon. Eventually, I only had a first degree tear that healed very quickly. I was able to have vaginal intercourse one month after birth and it didn't hurt a bit.
A word about Aniball/Epino: I knew it was highly controversial, and I decided to use ot anyway, alongside with perineal massages and other birth preparation. Perineal massages didn't work for me as I found it hard to reach. My partner was happy to help but, to be honest, in the weeks before birth I much prefered to spend our time together doing romantinc evenings, or social outings, or letting him go out with his friends rather than spending our evenings doing unpleasant perineal massages. I found Epino much more convenient as I could use it by myself during the day as I was on maternity leave: I would lie down comfortably and watch a serie while doing epino exercises for half an hour. Eventually I attribute the fact that I only got a first degree tear with only two stitches to the use of Epino (and the midwives who directed the pushing well). Worth every cent I spent, IMO.
The only advice I would give you is to research about birth and post-partum recovery and, whatever you decide, prepare yourself well and for all scenarios. Learn how to care for a episiotomy scar, how to prevent and treat piles, how to massage a c-section scar, stock up on food high in fibers to avoid constipation and piles (valid whether you opt for vaginal birth or c-section), buy witch hazel, epsom salt, a peri bottle, etc...
